In a large skillet, cook beef, onion and green pepper if desired over medium heat until meat is no longer pink; drain. Stir in the tomato sauce, beans, salt and garlic salt. Simmer for 8 minutes or until heated through.
Meanwhile, separate crescent dough into eight triangles; place in an ungreased 9-in. pie plate with points toward the center. Press onto the bottom and up the sides to form a crust; seal perforations.
In a large bowl, beat egg and 1 cup cheese; spread over crust. Stir 1/2 cup cheese into meat mixture; spoon into crust.
Sprinkle with paprika and remaining cheese. Bake, uncovered, at 375° for 20-25 minutes or until golden brown. Let stand for 5 minutes before cutting.
